Omg, Ogre Battle was epic. I thought I was the only person that had played that!

Regular NES - The Zeldas, Dragon Warrior, FF1, SMB3, Romance of the Three Kingdoms, Pro Wrestling, RC Pro Am, Excitebike, Wall Street Kid, Willow, Legacy of the Wizard, Pirates, Solomon's Key, and Bubble Bobble. I still have all of these and the NES.

If I had to pick one out of those I guess it would be Romance of the Three Kingdoms. Epic strategy game.

I don't know that I would like it anymore... it's pretty outdated now. I liked the amount of options in gameplay it had, the amount of units/upgrades, how gameplay choices changed your story (iirc, at the time that and Chrono trigger were one of the first few games to do that) and the depth of strategy.
